Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

The Ultimate Science Kit

Is that a radiation burn on the poor kid's face?
From Oak Ridge Associated Universities: "This was the most elaborate Atomic Energy educational set ever produced, but it was only only available from 1951 to 1952. Its relatively high price for the time ($50.00) and its sophistication were the explanation Gilbert gave for the set's short lifespan. Today, it is so highly prized by collectors that a complete set can go for more than 100 times the original price.

The set came with four types of uranium ore, a beta-alpha source (Pb-210), a pure beta source (Ru-106), a gamma source (Zn-65?), a spinthariscope, a cloud chamber with its own short-lived alpha source (Po-210), an electroscope, a geiger counter, a manual, a comic book and a government manual 'Prospecting for Uranium.'"
